ARLINGTON, Texas (AP) Heisman Trophy winner Johnny Manziel tiptoed along the sideline for a 23-yard touchdown on the Texas A&M's opening drive and the 10th-ranked Aggies led No. 12 Oklahoma 7-3 after the first quarter at the Cotton Bowl on Friday night.

Playing his first game since becoming the first freshman to win the Heisman, Manziel eluded tackles for a 5-yard gain on the first play. He was back to pass on a third-and-4, and eventually rolled to his left and took off for a 24-yard gain. His touchdown came on what started as another pass play on third-and-9.

Manziel rolled to his left and took off. When he juked around a defender and got near the sideline, he tiptoed to stay in bounds and punctuated his score with a high-step over the pylon for a quick lead.

Officials reviewed the touchdown play, but it was clear by the replay shown on the huge video screen above the Cowboys Stadium field that Manziel, who had three carries for 52 yards on the 75-yard drive, stayed in bounds.

The Aggies, with first-year coach Kevin Sumlin and their young star quarterback, are wrapping up their first SEC season after leaving the Big 12. The Cotton Bowl is the only postseason game matching teams from those two power conferences.

Oklahoma is in the Cotton Bowl for only the second time.

Sooners quarterback Landry Jones made his 50th career start, and came at the same place he made his Oklahoma debut in the 2009 season opener when he replaced injured Heisman Trophy winner Sam Bradford.

Oklahoma went 69 yards in 16 plays on its opening drive of the game, settling for a 23-yard field goal by Michael Hunnicutt. That came after Blake Bell, the Sooners' short-yardage quarterback specialist, was stuffed twice in a row from the 1.

This is the first bowl matchup between the former Big 12 rivals, but the 17th consecutive season they have played each other.

The Sooners have won 11 of 13 since Bob Stoops became their coach.

Sumlin was the A&M offensive coordinator in 2002 when the Aggies upset the top-ranked Sooners. The next year, Sumlin was hired by Stoops as an assistant, and he stayed there five seasons before going to Houston as head coach and then the Aggies.
